Used for functions
such as backlight
control
Note: *2 Connect an external resistor Rosc and an external capacitor Cosc between the OSC pin and GND when
selecting the RC oscillator operating mode and connect a current protection resistor Rg (2.2 to 22kΩ) between
the OSC pin and the external clock output pin (external oscillator) when selecting the external clock operating
mode (see the note on the OSC pin peripheral circuits).
